Formae speciales of Leveillula taurica (Lev.) Arn. infecting peppers and eggplants in Ghana

(...)Isolates from peppers readily infected both eggplants and Capsicum peppers in artificial inoculations. Eggplant isolates infected eggplants but, in general, failed to infect the peppers. Conidia collected from infected leaves of eggplants were consistently broader and shorter than those collected from infected pepper plants. Conidia produced after successful cross-inoculations retained their original form and dimensions. Isolates could not be differentiated on the basis of germ tube characteristics
